The aligning detail because it is fully describedin the joint appins are preferably made of substantially the 'plicationof applicant and Paul '0. Unger filed same :diameterias-the diameter ofthe apertures March 16, 1933 under 'Serial No. 66L080. 20 so that :thesheets fit .snugly on the aligning pins. The aligning pins 2| extendfrom the cover plate I! in a plane parallel to the plane of the lowerexposed portion of the rings I, I2 so as to facilitate engagement of thesheets and pins. The lateral movement of this portion of the rings inopening and closing is so slight, and the rings 'are so much thinnerthan the pins, that the parallelism between the pins and the lowerportion of the rings is substantially maintained in either open orclosed position. The upper edge of each aligning pin 2| is beveled, asindicated at 22, to further facilitate the impalement of the sheets|9"on the pins. T

In the embodiment of Figure 3, thealignin pins 2| are secured to anotherwise conventional ring metal cover plate 23. The outer edges 24 ofi lower exposed portion of therings is more ac-" curately maintainedthan in the embodiments where the aligning pins are not moved. InFigures 5 and 6, the ring metal 1 is provid with a cover plate 28 thathas the end portions ofits edges embracing the curved metal plate 'IIIand lying between the edges of the plate "and the reinforcing member'l'he intermediate edge portions 29 ofthe cover plate project beyond theedges of the plate 0 asclearly shown in Figure 5. Each edge of the ringbar is provided with a metal plate member-33 apertured to fit over thering sections l2. The aligning'pins 2| are secured to the members 30 inthe same'max'mer as in the case of the cover'plates i1 and 23; :Eachmember 30 has a plurality-of metal clips 3| weldedor riveted thereto andadapted to embrace the edgeportions-29 ofthe co'ver' plate. The clips"3| are loose'enough to'permlt transverse movement of the members 30relative'to the cover plate. When the rings are opened or closed-themembers 30,and consequently-the aligning pins 2|, are moved with'thering sections just usinthe embodiment of the invention. illustrated inFigure 4. i A In'order to attain speed and accuracy in'com puting datafrom sheets mounted on a summary board; it is not sufiicient merely tohave thesheets aligned properly, but it is also necessaryito have theline guide parallel with the line of figures being summarized. My lineguide'mechanism includes aline guide 32 rigidly secured to'a housing 33adapted to travel up and downs. rod 34 spaced from one end of the flatplate member 2 and secured in place by meansof a pair of fiat strips 35,36 (Figure 1) extendingirom one end of the plate member 2 adjacent'thetop and bottom, respectively. The rod 34 is secured'to'the strips 35, 36by means of screws or rivets. zA;por-,

. tion of the'peripheral surface of the rod 34 is 7, plate 38 by meansof the studs 4|, 42.

serrations 31. A pair of coiled springs 44, 45- mounted between theplate 38 and the housing: 33 exert a constant force against the plate 38to maintain the roller 40 in positive engagement with the serrations 31.The springs 44, are positioned by means of the studs 46, 41. One end ofthe stud 42 is extended beyond the front wall of the housing 33 andcarries a knob '43 which may be rotated-to move the housing along therod 34. The aperture in the housing through which the stud 42 passes isslightly elongated, as

"indicated at 42, Figure 7 for a purpose tobe hereinafter described.

'mounted in the housing 33 on the opposite side of the rod 34 from theplate 38 by means of a The stud 52 is spaced centrally of the plate 5|so that the plate 5| maybe pivotally moved around the stud 52 as acenter. Another roller 531s mounted in the plate 5| adjacent its upperedge by means of a stud 54. A threaded stud 55 is rigidly secured to theplate 5| adjacent its'lower edge and extends through one wall of thehousing 33. A threaded adjusting nut 56 is mounted on the portion of thethreaded stud 55 outside the housing 33. V

-. The angularity 01' the line guide 32 is adjusted the housin thenut'56 is rotated so' as to move the lower; edge of the plate 5| to the1ett(Figure 8). .Since the rod 34 is fixed, the roller 53 cannot movetothe right, and since the housing and plate 5| aresecured together bythe stud 52, the plate5| acts as a lever or the second class and pullsthe upper edge of the housing to the left.

-The lower edge of the housing cannot move any substantial distance tothe left because the slot42' (Figure 7) is elongated only very slightlyand the right end 01' the slot 42" soon contacts with the stud 42. Inview of the fact that the roller 49 is fixed to the housing and cannotmove. to the right because it is in contact with-the'rod 34 which isalso fixed, the roller" acts as a pivot point for the housing. Theportion of the slot 42' extending to the left of the stud 42 permits theslight movement of the housing with respect to the stud 42 necessary topermit. the counter:-

housing through which the rod 34 passes are sufficiently large to allowthev slightmovement of the housing necessary to adjust the angularity ofthe line guide. 7

The angular movement .of the housing: and line guide abovementionedcompresses the spring 44;

When the; nut 56 is moved in the opposite direction from that describedabove, the spring 44 expands and moves the upper .edgeot the housing totheright (Figure 8).- The lower edge ofthe housing is prevented frommoving to the right by the roller 43 which is fixed to the hous-i ingand is-in contactwiththe rod 34. Accordingly the housing ispivotallymoved in clock wise direction and the free end of the line guide ismoved downwardly. Obviously, the degree. of angular movement of the lineguide in. either direction can be controlled accurately by means of thethreaded adjusting nut.

While I have described my invention in detail, it will be understoodthat the description thereof is illustrative, rather than restrictive,as many details may be modified or changed without departing from thespirit or scope of my invention. Accordingly, I do not desire to berestricted to the exact construction described, except as limited by theappended claims.

I claim:

1. In a ring bar for summary boards, a pair of toggle plates, aplurality of sheet retaining rings on said toggle plates, and aplurality of aligning pins intermediate said rings.

2. In a ring bar for summary boards, a pair of toggle plates, aplurality of sheet retaining rings carried by said toggle plates, acover plate, and a plurality of aligning pins carried by said coverplate.

3. A ring bar for summary boards, a pair o f toggle plates, a pluralityof sheet retaining rings carried by said toggle plates, and a pluralityof aligning pins intermediate of said rings, said aligning pins beingadapted to move transversely when said sheet retaining rings are openedor closed.

4. In a ring bar for summary boards, a pair of toggle plates, aplurality of rings on said toggle plates, a strip mounted on said rings,and a plurality of aligning pins carried by said strip.
